90 Gal American Cichlids.

This is going to be a Blog charting the growth/progress of my Cichlids in the 90gal tank. Hopefully to give others an idea of how big/fast these guys can grow, and also of any aggression and compatibility issues I encounter along the way to them growing up. I'll include Photos so you can see the difference in them as they grow.

First Fish, 20.12.08. Pair of Oscars.

These were the first fish I decided upon, a pair of Red Oscars. They were around 2 inchs long at this stage and got on very well together. At this stage they were going to be the only fish in the tank..........

One month later, they'd grown around an inch each, and still got along well. No problems so far........

Not long after this however, the bigger of the two decided that maybe he didn't want to share the tank at all and began to pick on the smaller Oscar. At first there wasn't much to it, just a nip here and there, and the odd lunge at him, but before long the smaller of the two was to scared even to come out and feed. I decided this wasn't fair on him, and gave him away to a friend of mine, who had just got a 90gal for himself and was looking for an Oscar. So that left me with a bit of space to play with. I didn't think another Oscar was a good idea, so after a bit of thought, and discussion on Fishlore,(especially with Amanda and Shawnie!), I decided to try a couple of Jewel Cichlids, which are known to be aggressive and able to stand up to much bigger fish. Here they are on their first day.

After a couple of weeks the Jewels had settled in nicely and coloured up well. The Oscar didn't seem to mind sharing with them at all, possibly because they were so much smaller than him, and thus didn't pose a threat in his eyes. Encouraged by this, I decided to risk another smaller Cichlid, this time a Blue Acara........

The Acara did very well too, and a few weeks later I was lucky enough to pick up four baby Convicts. I decided to sell 3 of them, and kept the biggest, most aggressive male. He's the smallest fish in the tank, but NOBODY picks on him, he'll even challenge the Oscar for food, who is literally 20 times his size.

All this while I had been trying to find a Jack Dempsey, but with no success. Finally my LFS found on for me. He was in poor shape but as you can see from the pics, he soon recovered well and coloured up nicely. He is by far my most aggressive fish now, only bossed around by the Oscar, again only because of size though............

As of today then the final stocking list of my tank is 1 Red Oscar-7 inches, 1 Jack Dempsey-3 inches, 3 Jewel Cichlids-3 inches, 1 Blue Acara-3 inches, 1 Convict-2 inches. All of the fish get on as well as you might expect in an aggressive Cichlid tank, there's the odd argument but nothing major. Hopefully they'll continue getting along as they reach full size. The tank runs a wet and dry hood filter and a 5000ltr/per hr external Cannister, as even at this size they create a lot of waste. If I think it needs it, I'll add another filter as they grow. This is Brute now, 5 months after I first bought him home. That's 1 inch of growth per month, to give you some idea of how quickly Oscars grow, and why it isn't acceptable to keep them in a small tank, even for a short time.

Great blog Nick..
I love to see the progress on fish as they grow and change. Your red Oscar, Brute is really a handsome thing, great markings. I have seen the Reds at my LFS and between the tigers and the reds.. its a hard choice on which is nicer looking. Your boy is gorgeous. Guess it was just as well that you gave away the other Oscar tho, in that size tank with the other fish, it may have been just a wee bit cramped in there.
Keep up the good work, your tank looks great! Look forward to future photos of the 'kids' as they grow.

Green Water

The water has turned green, I'm hazarding a guess at more exposure to direct sunlight at this time of year. After some great advice from Lucy and Carol, I will be doing a Blackout for a few days, hopefully this will sort the problem!

Love the tank Nick! Let us know how that green water does.
Listing the progressive sizes and growth rates is very helpful thanks

HI Nick,
I had to do that to my 55 awhile ago and it actually worked. Only thing different was that my fish at that time were being moved to a new tank, so I didnt have to cover them up as well. After four days I took the black plastic off and the water was clear again.
Best of luck with your own black out of the tank and I'm sure everything will work out fine.

Remember to do a large water change afterwards to remove any dead algae that may be in the tank.

Black Out

Yesterday I covered the tank. The fish don't seem to mind too much, as long as I still feed them! I'll give it another day and see how it's getting on!

Things seem to have gotten a little too rough for the Acara so I've removed him. He was getting constantly bullied by the Jewels and Convict, and although he tried to stand up for himself he was outmatched. I've had to change stocking in my other tanks to accomodate him, so he's gone into the 39gal with the Angels, Kribs and large Platies. Everything seems fine in there for now, so I might have a think about getting another fish to go in the 90gal. It'll have to be pretty tough and able to stand up for itself. Any ideas?

I'd absoloutly LOVE a Green Terror, but I've never seen any ANYWHERE over here. A terror would be perfect! Someone in town is selling young Flowerhorns, what are they like?
 

Shawnie

Member
flowerhorns are just AMAZING!!!!! but not sure they can keep up with your guys...all the ones my buddy has, are docile for your troops...but maybe an adult could swing it?

they are super expensive here...$50 for a 4 inch baby

The ones for sale here are unbelieveably cheap compared to what I usually pay for fish. $30 for a 4 inch Juvie. But I don't fancy it's chances if they're usually docile.......It's not the Dempsey and Oscar that are the aggressors, it's the Jewels and especially the Convict, he's a vicious little bugger!
 

Shawnie

Member
they are more like an oscar and dempsey kinda personality(flowerhorns) do you have a dempsey in there also? they would be good...especially if you can find a bigger one......I know about cons ...got my males in with africans ...should see my boys now ...I swear one looks like a flowerhorn with his bull bumped head..hes a good 6 inches and then some...no way anyone can order you a green terror? even then , you would need one about the same size as your con or he might even take that bad boy on ...funny how much fish are in some areas...crazy for sure

At moment there's Brute,plus a 4 inch Dempsey Male, and the Jewels and Convict. The Con is the smallest, only about 2 inches, but also the most aggressive. I think the Flowerhorns are about 4 inches. How big do they get. Can't seem to find any info on them?

Heres the pic from the add. I've bought fish from the seller before, all in good condition.

heres a few links...check out the golden monkey..amazing fish!@
my buddy has one that's about 11 inches right now...not sure how big they can get but from what I have read, same size as oscars...

I want a Golden Monkey! Do you think I'd be pushing it for space with a Flowerhorn? That would be the Oscar, Flowerhorn and JD in a 90gal, plus the 4 smaller guys.........
 

Shawnie

Member
the smaller ones aren't a bioload issue...and depending on how big your flowerhorn and oscar get, it could be down the line...is 90 gals the biggest you are going to go? with extra filtration (as I'm sure you have as you were going to have 2 oscars) its doable but with the jd in there, it could be an upgrade in the future but I agree the golden monkeys are amazing ..

Nick G

The Filtration is superb and I do water changes twice a week. As for an upgrade, yes there will definitely be one down the road. I was looking at a 125gal at the weekend, but the wife refused as we are expecting our second child in october. (It cost $2000!)
 

Shawnie

Member
ouch!!!!! do you have a craigslist around there? I know its world wide....(NOPE I'm not helping with the MTS ;D )

fish vs babies...quite a dilemma haha...

wonder if your buddy has the goldens? that would be awesome...id pay about $200 for a nice one here...

Updated Pics

It's been a while since I've updated the Blog so here's some recent pics of the fish in the 90gal. I rescued a Severum from the LFS a few months ago. He's taken to the tank brilliantly and has become best friends with Brute, they spend all day together swimming up and down the tank. All of the other fish are doing great too. Cresswell the Dempsey has moved into the large cave, and is growing fast now. He'll be catching Brute up size wise before to long!

Picture Time!!!!!!!

After a good clean the tank actually looks HOW I WANT IT TO!!!!!!!!!!.......... it won't look like this for long though. By the time I get up all the plants will have been ripped out, and most of the sand shovelled to the front of the tank for some bizarre reason that only Brute knows. I mean, I could understand it if they were real plants. But they're only imitations! And poor imitations at that. I'm watching him now...........he just ripped a piece off one of the plants and tried to eat it, spat it out, then went and ripped another piece off! If he couldn't eat the first piece why did he think the second would be edible!!!!!!!!!!!!! Sorry for the rant

Brute just wants to make sure it still taste nasty! He doesn't want to miss out on anything tasty

Nick, so sorry Brute's giving you a hard time, but that tank looks FANTASTIC and Brute is absolutely gorgeous! What species is that little fellow in there with him? He's a cutie!
